This white paper examines the effect of fluorinated thermoplastic processing aids in the film processing of recycled polyethylene resins. Both melt fracture elimination and pressure reduction were observed when a Kynar® PPRA was added to a recycled polyethylene film process. This data suggests that film converters looking to increase recycled polyethylene output, or the per cent of recycled polyethylene content in their process, can consider adding a Kynar® PPRA to increase their processing efficiency.
